which can be found here :

http://www.trirand.com/blog/

the version released with this package is 3.8.1

Use as a grid

in the view controller

from tw.jqgrid import JqGrid
colNames = ['ID','Title', 'Synopsis']
colModel = [
            {'name':'id', 'index':'id', 'width':20, 'align':'right'},
            {'name':'title', 'index':'title','width':100, 'align':'left'},
            {'name':'synopsis', 'index':'synopsis','width':580, 'align':'left', 'sortable':False},
           ]
search_options = {
      "caption": "Search...",
      "Find": "Find",
      "Reset": "Reset",
      "sopt" : ['cn', 'bw'],
      "closeOnEscape":True,
}

navbuttons_options = {
                      "view":False,
                      "edit": False,
                      "add": False,
                      "del": False,
                      "search":True,
                      "refresh":True,
                      }

grid_local = JqGrid('movie_list', url='fetch', caption='Movies',
            colNames=colNames, colModel=colModel,
            rowList=[5,10], rowNum=5,
            sortname='title',
            viewrecords=True,
            width='auto',
            height='auto',
            shrinkToFit=True,
            search_options = search_options,
            navbuttons_options = navbuttons_options,
)


class MoviesController(BaseRestController):

    @expose('project.templates.movies.get_all')
    def get_all(self):
        pylons.c.grid = grid_local
        return dict(page='all movies')

in the template

${tmpl_context.grid()}

now to feed data we need a controller:

from math import ceil

@expose('json')
def fetch(self, page=1, rows=10, sidx=1, sord='asc', _search='false',\
          searchOper=u'', searchField=u'', searchString=u'', **kwargs):
    offset = (int(page)-1) * int(rows)
    q = Movie.query
    search_bool = eval(_search.capitalize())
    if (search_bool):
        field = str(searchField)
        field_attr = getattr(Movie, field)
        if searchOper == u'cn':
            q = medias_q.filter(field_attr.contains(searchString))
        if searchOper == u'bw':
            q = q.filter(field_attr.startswith(searchString))

    result_count = medias_q.count()
    total = int(ceil(result_count / float(rows))) # total nb of pages
    column = getattr(Movie.table.c, sidx)
    movies = q.order_by(getattr(column,sord)()).offset(offset).limit(rows)
    rows = [{'id'  : movie.id,
             'cell': [movie.id,  '<a href="/medias/%s/">%s</a>' % (movie.id, movie.title),
                      movie.synopsis]} for movie in movies]
    return dict(page=page, total=total, records=result_count, rows=rows)

Note

this is written for an elixir model, adapt to your need

design it:

tw.jqgrid rely on tw.uitheme for its design, the smooth theme is the default you can use any other theme, or roll your own theme

below a code snippet on how to do that:

from tw.uitheme import lefrog_css, peppergrinder_css
from tw.jqgrid import jqgrid_css, jqgrid_search_css

class CustomGrid(JqGrid):
    css = [peppergrinder_css, jqgrid_css, jqgrid_search_css]

grid_local = CustomGrid(.....
